S5. The diagram below shows a billiard cue ball A of mass m which is initially moving along the y axis with speed v = 2m/s. The ball A hits a stationary ball B of mass m. Post collision, the ball B moves with speed vị = at angle with the negative x axis as shown. You may need cos 30° = v³, sin 30° =;, cos 60° = ; 1m/s at angle 0 = 30° to the positive x axis and ball A moves with speed v2 and sin 60° V. You may leave your answers in terms of radicals if necessary. Final Initial (a) Find the speed v2. (b) Is the collision elastic? You must justify your answer with a calculation.
